BICYCLE-ALARM.

SPECIFICATION forming part Of Letters Patent N0. 636,833, dated November 14, 1899.

Application filed April 3, 1899. Serial No. 711,622. (No model.)

To all whom, it may concern;

Be it known that I, DANIEL NEI, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Bicycle-Alarms, of which the following is a specification.

My invention relates to improvements in revoluble grips attached to and arranged for ringing bicycle-bells; and its objects are, first, to provide a revoluble grip that may be applied to ring any of the various forms of bicycle-bells, Whether constructed to be actuated with a reciprocating or a revoluble actuating mechanism, and, second, to avert the danger of straining or breaking the lever upon a reciprocating bell or of allowing the grip to revolve too far on a revoluble bell. these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of a grip and the end of a handle-bar on the line (.8 x of Fig. 2. Fig. 2 is a side view of my grip,

showing its connection with a revoluble bell.

Fig. 3 shows the same connected with a reciprocating bell. Fig. 4 is an end view ofa grip, showing the stop mechanism, Fig. 5isaplan and Fig. 6 is a side view of the jam-nut or packing-screw that holds the packing in the end of the grip-sleeve, and Fig. 7 is an end View of the clamp that engages the inner surface of the handle-bar to hold the grip securely thereto.

Similar letters refer to similar parts throughout the several views.

A, represents the end of the handle-bar.

B represents the grip, and I represents the bell. In the construction of this grip I form a metallic sleeve D, somewhat larger than the external diameter of the handle-bar, so that it will turn freely thereon without coming in contact therewith. The outer end of this sleeve is formed to cover the end of the handle-bar and is provided with a central aperture a, through which the screw F passes, forminga bearing to perfectly center the end of the grip upon the handle-bar and hold the sleeve from contact with the end thereof. This screw passes through the spool O O and the hub of the spring-clamp E, which is pro- Vided with a screw-thread for the reception I attain of said screw and by means of which it may be drawn upon the inclined surface of the end 0 of the spool with suflicient force to cause it to press heavily against the inner surface of the handle-bar and engage therewith to hold the grip securely to place. The other end of this sleeve is spun out to form the shoulder and cup D, and the inner surface of the cup, beyond the shoulder, is provided with a screw-thread arranged to receive and mesh freely with the screw-thread on the surface of the jam-nut G. (Shown in Fig. 6.) I place a gasket, of leather or other suitable material, in this cup, as shown atI-Iin Fig. 1, and force it to place with the jam-nut, by means of which I can exert more or less pressure, as the case may demand. This gasket is designed, first, to act as a bearing to support this end of the grip and prevent it from coming in contact with the handle-bar; second, to produce sufficient friction, so that there will be no inconvenience incurred by reason of the grip turning too easily; third, to prevent water or oil flowing through between the grip-sleeve and the handle-bar, and, fourth, to form a smooth bearing at this line and prevent the turning of the grip in the direction of the arrow in Fig. 4 will sound the bell upon one stroke and the spring-actuated return of the lever will ring the bell upon the other stroke of the hammer and will draw the grip around to its normal position. (Indicated in Fig. 4.)

To avert the danger of straining or breaking the link i or the lever z" or of turning the grip too far when used with a rotary bell, I

place a short pin 0 on the surface of the back end of the spool, which projects out just far enough to pass through the end of the sleeve D, and in this end I form a short slot at in position to receive the pin and allow the grip to turn only the length of the slot less the size of the pin.

To facilitate placing the spool in place in the handlebar and to prevent it from turning when screwing the clamp to place, I form sharp inclined lugs c on the end 0 of the spool and lugs, as indicated at c, on the end C of the spool, it being understood that the spoolis made in two pieces, the portions 0 and 0 being separate and detachable.

The grip may be completed with corkoline, leather, or any other suitable material, the ends being protected by ferrules I) l) in the usual manner, the ferrule I) being provided with an aperture for the reception of the screw F. The body of the screw F is slim and is provided adjacent to the head with a shoulder of a proper length to pass through the end of the sleeve and the ferrule and clamp the grip firmly to the handle-bar and at the same time allow the grip to turn freely on the handle-bar.

The back wall or shoulder of the cup D is slightly inclined or angling, so that the forcing of the gasket H against it will at the same time force it toward the handle-bar, so that the degree of friction induced by the gasket may be controlled at pleasure.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent of the United States, is

1. In combination with the handle-bar of a bicycle, a revoluble grip, a supporting-sleeve within said grip, the outer end of said sleeve closed and the inner end expanded to form a seat for a packing or gasket, and a receptacle for a jam-nut, a clamp within said handlebar, a screw to engage the clamp to hold the grip to place, a connection between the grip and the bicycle-bell, a slot through the closed end of the sleeve, and a pin projecting from the end of the spool to engage therewith to govern the motion of the grip, substantially as, and for the purpose set forth.

2. In combination, a handle-bar, agrip, and a bell; a connection between the grip and the bell, a supporting-sleeve within the grip, a chamber in the end of said sleeve, a pliable packing within said chamber, a jam-nut to screw into said chamber to regulate the pressure of the packing upon the handle-bar, an

inclined shoulder to receive the packing, and 5d a stop for limiting the motion of the grip, substantially as and for the purpose set forth. I

3. In combination with a handle-bar and bell of a bicycle, a revoluble grip secured to encircle the end of the handle-bar, an annular gear-wheel on the grip to engage the actuating-wheel of the bell, a spool fitted to adjust itself to the inner diameter of the handie-bar, a flaring clamp fitted to be expanded by the end of the spool, and a screw passing through the ferrule of the grip, the spool and into the hub of the clamp to secure the clamp and spool to the handle-bar, and a shoulder on the screw to bear upon the end of the spool so that the clamp may be firmly set in the handle-bar without interfering with the revoluble motion of the grip, substantially as and for the purpose set forth.

4. In combination with the handle-bar and bell of a bicycle, a revoluble grip secured to 7c encircle the end of the handle-bar and connected to ring the bell when revolved, a spool,

a clamp, and a screw having a shoulder to secure the clamp inside of the handle-bar without binding the grip, and lugs and inclines on the spool to prevent it from turning in the handle-bar, substantially as and for the purpose set forth.

5. In combination with a handle-bar and bell of a bicycle, a revoluble grip secured to encircle the handle-bar and having an annu= lar gear fitted to mesh with the actuatingwheel of a bell, and an expansible clutch with in the handle-bar to secure the grip thereon, substantially as and for the purpose set forth.

6. In combination with a handle-bar, and a revoluble grip for ringing a bicycle-bell, a spool, an expansible clutch, a screw having a shoulder to engage the spool and allow the grip to turn freely, and lugs on the spool to prevent it turning in the handle-bar, substantially as and for the purpose set forth.
